NON-AGREEMENT STATE REPORT - STUCK SHUTTER
The following information was provided by the licensee via email:
" Marathon Pipe Line LLC and the Manufacturer, VEGA Americas, Inc., evaluated a [fixed gauge] device [OHMART/Vega Corporation Model SR-1A, S/N M5965. Cs-137 80 mCi ] on 05/02/22 to verify the operation of the shutter mechanism.
" During the evaluation of the device the VEGA FS Technician confirmed that the shutter mechanism would not close.
" The cause is internal mechanism failure of the shutter device.
" The shutter is in the Open position and won't close.
" The Open position is the normal operating position.
" There was and is no radiation exposure concern for Marathon Pipe Line LLC employees, contractors, visitors or the general public.
" Vega Americas, Inc. has been contacted for a path forward to order and install a replacement device as well as develop a plan and assist in the safe removal, isolation and disposal of this gauge."

AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE DISCONNECT
The following was received from the Illinois Emergency Management Agency (the Agency) via email:
"The Agency was contacted at 0830 CDT on 5/3/22 to advise that a radiography crew had a 55 Ci Ir-192 source disconnect from the drive cable while working at a site in Bradley, Illinois over the evening. The crew contacted their RSO and the source was successfully retrieved and placed into a shielded position. As the work was done after hours, there are reportedly no concerns over public exposures. Three MISTRAS staff recorded maximum exposures of 65 mrem on their [direct reading dosimeters] DRDs from the operation and have overnighted dosimetry for processing."

PART 21 REPORT - FAILURE OF AN EATON ELECTRICAL CUTLER HAMMER RELAY
The following information was provided by Framatome Inc. via email:
"Framatome Inc. (Framatome) supplied an Eaton Electrical Cutler Hammer, Inc. (Eaton) D26MRD704A1 Relay to Duke Energy Carolinas, LLC, McGuire Nuclear Station, that failed to change state during testing of their load sequencer. This relay was supplied as a safety related component by Framatome. A molded contact bar in the D26 top adder deck prevented a contact spring from settling into its proper position. Top adder decks manufactured between 2003 and 2022 were inspected for the existence of flashing, but no specific time frame where the excess flashing was found could be identified.
"Testing of additional relays with this similar excess flashing condition, by both Framatome and Eaton, showed that contact springs tended to stay in place and were unaffected by the excess flashing. There have been no past similar relay reports by Framatome customers despite there being at least 587 other relays with top adder decks supplied as commercially dedicated components. Eaton has also indicated that they have had no other reports of this condition or failures associated with it.
"The extent of condition determined that the failure is an isolated incident. Only one relay, supplied to McGuire Nuclear Station, failed to change state.
"In the future, as a precaution, the Framatome commercial grade dedication process will include the inspection of the adder deck contact bars. Relays containing contact bars with excess flashing will be rejected."
